Hi!
You can't do that.
You are going to cast an object to something that you
don't know what it is going to be.
Then what are you going to do with the object after that?
Do you know any method to call or what?
The whole code after that should be also "dynamic".
This sounds like you wan't to do a

Yup I figured that out ...
but how do I do a typecast when I have the class name in a String
variable during runtime. (I do NOT know the class name to typecast).

I've been able to make it sort of limp by using running it under the
"oldjava" launcher. It's not a pretty sight.

This isn't the right way to generate a .so file.
You need to use the -shared switch on gcc (I presume this is also
supported by g++, but you can use gcc to transform a g++-generated
.o file into a .so).

Hi Eric,
in JDK 1.1.x, you have to include the standard classes in the CLASSPATH.
Depending on your installation, include something like

necessary.
Another hint: swingall.jar contains all the other swing-related jars

Hi,
I wrote small animation application which uses multiple threads
and I have some problems running it on my Linux machine. Generally,
I do the following:
1. In one thread I calculate my image using MemoryImageSource method
(time-consuming task).
2. Stop and start my Animation using buttons.

Check your applet tag for codebase tag
Check to make sure your datbase driver is available in the directory where
your codebase is implied.
Make sure you database is on the same machine as the applet is loaded
from.

Applets can NOT open or write files, for security
I had the same problem trying to acces to my data base in oracle by an applet.
The reason could be this restriction see documentation on applet restrictions.
